ELEGTRICALLY-CONTROLLED LOCK.

Specification of Letters Patent.

Serial No. 432,540.

To all whom it may concern:

Be it known that I, ED\VARD MARVEL, of Philadelphia, in the State of Pennsyl- Vania, have invented a certain new and useful. Improvement in Electrically-Controlled Locks, whereof the following is a specification, reference being had to the accompanying drawings.

My improvement is particularly applicable to looks for safes or vaults comprising a rotary shaft which is required to be turned to a definite extent; for instance, said rotary shaft may be the tumbler arbor of a combination or permutation lock or the winding arbor of a time lock.

Although in a combination or permutation lock, such a rotary shaft is required to be turned alternately in opposite directions, and in a time lock, such a rotary shaft is required to be turned in but one direction; in either case, my improvement comprises the combination with a winding motor local to the lock, of an indicator motor local to means for controlling both motors, and remote from the lock; both-motors being so electrically connected as to be operated synchronously, so that the operator manipulating said controlling means may ascertain from the manifestation of said indicator, the precise position of rotation of the lock shaft being turned by the winding motor.

My invention comprises the various novel features of construction and arrangement hereinafter more definitely specified and claimed.

In the drawings; Figure I, is a diagram showing an arrangement of the electrical connections of my invention for operating a combination lock. Fig. II, is a front elevation of the winding motor and mechanism operatively connecting it with the lock arbor. Fig. III, is an end view of the winding mechanism shown in Fig. II. Fig. IV, is a front elevation of the indicator motor and mechanism connected therewith. Fig. V, is a fragmentary sectional view of one of the divided clutch shafts, taken on the line V, V, in Fig. IV.

Referring to Fig. I; the parts indicated below the line XX, are located within the safe in which the lock is employed, and the other parts are exterior thereto. The electric winding motor comprising the field 1, and the armature 2, is arranged to turn the lock arbor 3, by the wheel 4. The direction of rotation of said armature 2, is constant,

but said lock arbor 3, may be turned alternately in opposite directions by mechanlcal connection therewith, such connectlon being determined by the clutch magnets 6 and 7 c which are local to said winding motor. The electric indicator motor comprising the field 9, and the armature 10, is arranged to actuate the indicator dial 12, in synchronism with the rotation of the wheel 4; the direction of rotation of said dial 12, being determined by the clutch magnets 13 and 1.4, which are local to said indicator motor. The current is supplied through the leads 16 and 17, which connect through the fuse block 18, with the double-pole switch 19, whereby the current supply may be entirely out off from the apparatus. The leads 21 and 22, extend from said knife switch 19, to the doublepole push button 23, whereby said lead 22, is connected by the lead 24, with the field 9, of the indicator motor which is connected in shunt with its armature 10, by the lead 25. Said armature is connected by the lead 26, in series relation with the field 1, of the winding motor which is connected by the lead 27, in shunt relation with its armature 2, and said armature is connected. by the lead 28, through the resistance 29, and said push button 23, with the lead 21. Said push button 23, is normally spring pressed to break the circuit through the leads 24, and 28, but is pressed the lead 31, branching from the supply lead 22, to the switch 30, the lead 32, extending from said switch 30, to the magnet 14; the

lead 33, extending from said magnet 14, to

the magnet 7; and thence, by the lead 37, through the resistance coil 38, to the supply lead 21. Said left hand clutch magnet 13,

of the indicator mechanism and the left hand clutch magnet 6, of the winding mechanism may be connected in series relation when the switch blade 30, is shifted to the left to close the circuit from the lead 31, through the lead 39, to the clutch magnet coil 13, of the indicator mechanism, the lead 40, extending from said magnet 13, to the magnet 6, of the winding mechanism and the lead 41, extending from said coil 6, to the circuit breaker comprising the contacts 42, and 43, and thence, by the lead 37, to the supply lead 21, as above described. Said circuit breaker contacts 42, and 43, are normally closed to complete the. circuit, as shown, but are opened to instantly terminate the winding movement of the. lock when the lock member 45, is shifted, from the position shown, in the direction of the arrow marked thereon in Fig. I, which movement occurs when the lock is opened. In order to set the dial 12, to correspond with the position of the wheel 4, it is necessary for the operator at the indicator station to know the precise position of said wheel 4, at the winding station. Therefore, I provide a test circuit comprising the lead 46, extending from the supply lead 22, through the annunciator 47, at the indicator station to the test switch at the winding station, comprising the stationary contact 43, and spring contact 49, the latter being connected by the lead 50, with said lead 37. As shown in Fig. I, said wheel 4, of the winding mechanism is provided with the cam 51, which is coincident with'the initial point of said wheel, and which closes said test switch when said cam reaches a certain point in the revolution of said wheel 4; so that when the annunciator 47, is operated by closure of said test switch, the dial 12, may be set with its initial point corresponding with that of the wheel 4.

As shown in Fig. II; the winding motor armature 2, has its shaft 52, journaled in the bearing standards 53, extending at its opposite ends from the frame 54. Said shaft 52, has the beveled pinions 55 and 56, respectively engaging the gear wheels 57 and 58, on the clutch shafts 59 and 60, which are journaled in said standards 53, and in the standards 61. Said shafts 59 and 60, are respectively in alinement with the shafts 62 and 63, which are supported in the bearing standards 64, and 6-5, on said frame 54, and carry the bevel gears 66 and 67. Said bevel gears 66 and 67, are respectively engaged with bevel gears 68 and 69, carried at the respectively opposite ends of the worm shaft 70, which is supported in said bearing standards 64, and also in the bearing standards 71. Said worm shaft 70, carries the worm 73, which is engaged with the wheel 4, which is a worm. gear carried by the rotary lock shaft 3. Said clutch shafts 59 and 60, are provided with clutch sleeves 76 and 77 which are free to slide thereon but are caused to turn therewith by the pins 78 and 79, extending into the slots 80 and S1, ofsaid sleeves. Said sleeves 76 and 77 are respectively provided with clutch lugs 83 and 84, arranged to alternately engage the clutch studs 85 and 86, which respectively project from the shafts 62 and 63, in rigid relation therewith. Said sleeves 76 and 77, are provided with loose collars 83 and 89, pivotally connected by pins 90 and 91, with the clutch shifting lever 92, which is fulcrumed intermediate of its length on the stud 93, extending from said frame 54. The opposite ends of said lever 92, are in operative relation with the clutch shifting magnets 6 and 7 which are disposed in pairs supported by the brackets 95 and 96, extending from said frame 54.

As shown in Fig. IV; the indicator motor armature 10, has its shaft 102, journaled in the bearing standards 103, extending at opposite ends from the frame 104. Said shaft 102, has the bevel pinions 105 and 106, respectively engaging the gear wheels 107 and 108, on the clutch shafts 109 and 110, which are journaled in said standards 103, and in the standards 111. Said shafts 109 and 110, are respectively in alinement with the shafts 112 and 113, which are supported in the bearing standards 114 and 115, in said frame 104, and carry the bevel gears 116 and 117. Said bevel gears 116 and 117, are respectively engaged with the bevel gears 118 and 119, carried at the respectively opposite ends of the worm shaft 120, which is supported in said bearing standards 114, and also in the bearing standards 121. Said worm shaft 120, carries the worm 122, which is engaged with the dial 12, which is a worm gear mounted to turn freely on the stud shaft 123, in said frame 104, and is provided with a circular series of one hundred graduations 124, cor responding with the ordinary tumbler dial of a combination lock. The index 125, projects in stationary relation with said frame 104, in correspondence with the index point of the lock dial. Said clutch shafts 109 and 110, are provided with clutch sleeves 126 and 127, which, though free to slide thereon, are caused to turn therewith by the pins 128, and 129, extending in the slots 130 and 131, of said sleeves. Said sleeves 126 and 127, are respectively provided-with clutch lugs 133 and 134, arranged to alternately engage the clutch studs 135 and 136, which respectively project from the shafts 112 and 113, in rigid relation therewith. Said sleeves 126 and 127 are provided with loose collars 138 and 139, oivotally connected by pins 140 and 141, with the clutch shaft lever 142, which is fulcrumed intermediate of its length on the stud 143, extending from said frame 104. The opposite ends of said lever 142, are in operative relation with the clutch shifting magnets 13 and 14, which are disposed in pairs supported by the brackets 145 and 146, extending from said frame 104.

The apparatus above described, as arranged in Fig. I, is adapted to operate a combination lock of which 3, is the tumbler arbor and 4, a wheel corresponding with the ordinary graduated disk by which such an arbor is turned. As shown, the lock arbor 3, is in its initial position with the cam 51, closing the test circuit and operating the annunciator 47, to manifest said position to the operator local to the means for electric ally controlling the apparatus as above described. The indicator dial 12, being set in a position corresponding with the initial position of said lock wheel 4-, aforesaid, and the switch blade 30, being set, as shown, to simultaneously operate the right hand clutch magnets 7 and 14-; both the wheel 1, and the dial 12, are turned synchronously to the right, while the operator holds the switch 23, closed as shown. Vhen said movement has continued until the desired number is reached, the operator may reverse the direction of rotation of said wheel at, and indicator dial 12, by shifting the switch blade 30, to the left, first breaking the circuit through the leads 31 and 32, and thus disconnecting the right hand magnets 7 and let, and the clutches controlled thereby. Then, by further movement to the left, said switch blade 30, establishes the circuit through the left hand clutch magnets 13 and G. hen the lock arbor 3, has been thus turned to the desired extent, the operator may disconnect all of the clutch mechanisms and thus terminate the turning movement, by shifting the switch blade 30, to its central position; the two motors continuing to rotate until the operator releases the push button 23, which has been held closed throughout the turning operation aforesaid. However,irrespective of the position of the switch blade 30, the turning movement of the lock arbor is instantly terminated automatically when the lock is opened, because the movement of the lock member 45, consequent upon the opening movement of the lock, breaks the circuit through the clutch magnets, by separating the contacts 42 and 13 It being understood that my invention may be applied to wind one or more spring arbors of a time lock, suitably connected with the wheel a, it may be observed that as such use does not require the reversal of direction of rotation of the wheel 4; the left hand clutch magnets 6 and 13, and the circuits connecting them with the other parts of the apparatus may be omitted. In such use of my invention the lock member 45, may be operatively connected with the usual automatic stop mechanism of the time look so as to break the circuit and terminate the winding movement when the lock is fully wound. The resistance coils 29 and 38, are merely employed to adapt the circuit shown in Fig. I, for connection with an ordinary electric lighting circuit, and it is to be understood that if a battery or other suitable source of energy is employed, said resistance coils may be omitted.
